Without spending any money on the game, you'll only collect one legendary crest per month. Even purchasing a battle pass will only provide you with Diablo IV Gold the equivalent of two legendary crests each month. Beyond that, you need to purchase them from the source. Legendary crests are priced somewhere between $2 and $3 each. The sheer amount of gems required for your character's best equipment and abilities, particularly when you consider the extremely low drop rates for five-star gems is the reason why the price of maxing your character's abilities within Diablo Immortal has been estimated at somewhere between $100,000 and $50,000- potentially even more, in the case of getting into the gem resonance system. (Rock Paper Shotgun comes with an extensive breakdown of costs that lands at the more conservative end of this scale.)
Diablo Immortal has been given an extremely rough ride the business model it is based on (perhaps disproportionately), considering popular free-to-play rivals like Genshin Impact and Lost Ark are not without similar gacha mechanisms to draw in huge-spending "whale" gamers. Diablo's fame and reputation with a large PC gaming audience, which has been built over a quarter of a century, is definitely an element. But , it's also true Diablo's gaming system is notoriously problematic and the very nature of Diablo games may have some connection to that.
When you buy legendary crests, remember that you're not buying a single roll of the dice as you buy the FIFA Ultimate Team card pack like. You are purchasing the chance to roll the dice to tap into the game engine and tweak the drop rates (slightly) in your favor. Its addictive gameplay mechanics are not separated from the addictive gameplay mechanics, but instead tied directly into combat and loot drops in the game. Diablo is uniquely well-positioned accomplish this. As my colleague Maddy Myers pointed out, the games that are heavily focused on loot have always had a slot-machine quality, which Diablo Immortal's model of business makes an actual.
Blizzard has made it a point to emphasize that the monetization of Immortal can be ignored until the final game and it's true and claims that the majority of players are enjoying the game without spending even a cent, which is feasible. However, it's a bit naive to claim that the greatest enjoyment in Diablo games resides in exploring the story instead of trying to max out your character. It's equally absurd to claim that the games have created an urge to hit the power cap for their players. For those who have a tendency toward addiction to gambling, to the addictive aspects of Diablo's item gameand, perhaps either of them -- the legendary crest system could be an abuser and could be extremely damaging.
For those who don't it just makes Diablo 4 Gold more difficult to play.
